Abstract (en)

Tuneable linear-antenna transponders and methods of making and using thereof are described herein. In some embodiments, the transponder includes two radiators formed of a conductive material, wherein the radiators may be identical or different. In some embodiments, the radiators are divided into a multitude of segments, wherein each segment is in the form of a linear segment or helical spring segment or cylindrical segment. In some embodiments, two of the consecutive segments are different in either shape and/or pitch of the helical spring. The distinct transmission line segments provide additional degrees of freedom, which enables finer/improved tunability of the antenna resonance.
